Pearl Jam had not yet hit the big time at the time of this concert. Capacity was 4000 people I believe. Eddie Vedder has since worn this on stage many times. It's in pretty much mint condition. I believe it's a sought after shirt, but I'm not sure about a dollar figure. Any thoughts?

Just found a lot of old rock and movie shirts from 1978-1982, all in near perfect condition. Many have radio station logos on them and seem to be one offs. All have authentic tags (screen stars, knits, hanes beefy, etc.) and are size L or XL. Any help on the values would be appreciated greatly ...
